Pro-Israel leaders in the United States, Britain and Australia are warily watching the unfolding of the phone-hacking scandal that is threatening to engulf the media empire of Rupert Murdoch, founder of News Corp.

Murdoch’s sudden massive reversal of fortune—with 10 top former staffers and executives under arrest in Britain for hacking into the phones of public figures and a murdered schoolgirl, and paying off the police and journalists—has supporters of Israel worried that a diminished Murdoch presence may mute the strongly pro-Israel voice of many of the publications he owns.

“His publications and media have proven to be fairer on the issue of Israel than the rest of the media,” said Malcolm Hoenlein, the executive vice-chairman of the Conference of Presidents of Major American Jewish Organizations. “I hope that won’t be impacted.”

Murdoch’s huge stable encompasses broadsheets such as The Wall Street Journal, the Times of London and The Australian, as well as tabloids, most notably The Sun in Britain and the New York Post. It also includes the influential Fox News Channel in the United States and a 39 percent stake in British Sky Broadcasting, or BSkyB, a satellite broadcaster. Murdoch founded the neoconservative flagship The Weekly Standard in 1995, and sold it last year.

Jewish leaders said that Murdoch’s view of Israel’s dealings with the Palestinians and with its Arab neighbors seemed both knowledgeable and sensitive to the Jewish state’s self-perception as beleaguered and isolated.
